Yariv, Hi....
A good guide to several of the best wine bars in New York was posted by Aeyal Gross on his blog at
http://www.notes.co.il/gross/29234.asp . I know you read Hebrew so you will have no problem reading that piece. Among the places he lists and I have since visited and recommend:
Vintage New York Wine Bar, 482 Broome St (at Wooster), 212-226-9463
Morrel Wine Bar, 1 Rockefeller, Plaza, 212-262-7700
Cru, 24 Fifth Ave (at 9th St), Tel 212-529-1700
Enoteca I Trulli, 212-481-7372, 122 E. 27th St (between Lexington Ave and Park Ave
As to restaurants, New York, like Paris, has become a moveable feast and one could (and several have) write a book entirely about dining out in that great city. I'll limit myself to two of my favorites: The Union Square Café and the Grand Central Oyster Bar.
Worth taking a look though at the thread on the "old forum" at
